MICHAEL HICKS, OF NEW YORK, N. Y.

CAR-LAMP.

SPECIFICATION forming part of Letters Patent No, 352,243, dated November9, 1886.

Application tiled October 23, 1885.

To all whom it may concern:

Be it known'that I, MICHAEL HICKS, a citzen of the United States,residing at the cityV of New York, in the county and State of New York,have invented certain new and useful Improvements in Lamps, ol' whichthe following is a specification.

My inventiony relates more particularly to plicable to lamps insteamboats and other public places, and it consists of devices for.holding the lamp-"shade and vsecuring and steadying the upper portionof the lamp-A chimney, my improvedconstruction being such as to admitIof the removal and replace disturbing eithe-r lamp-shade or lamp-burner.

I have illustrated luy-invention bythe accompanying drawings, in whichFigure 1 is an elevation showing an upper section of a carlamp havingconnected therewith iny'improvements. Fig. 2 is likewise anelevationrepresenting the chimney-holding device thrown upward ordisconnected from the chimney for the purpose of showing the springswhich hold and steady the chimney when in its normal position. Fig. 3 isa detail showing one element of my invention, consisting of a clainip#of which the shade of thev lamp is supported and heldinjvpropenposition. Fig. 4 is anring `which encrcles the top of thechimney, and with which the springs are connected, likewise showing thespring device, constitut-` ing a further elementA of my invention, whichanism by which position.

Like letters refer to like the several views. y

A indicates the supporting-frame of the lamp, secured to the roof B ofthe car in any suitable manner.

G indicates the lamp-shade.

D is a pipe extending through the ceiling of the car, through which thesmoke and gases from the lamp escape.

E is that portion of the lamp which extends above the chimney and actstoconvey upward the products of combustion in the direction of the upperpipe or ventilator, D.

said cap or ring is held in parts throughout Serial No. 180,759. (Nomodel.)

threaded in opposite directions, and fitting, respectively, into screwthreaded holes in the two ends of the spring c. The shade C is placedwithin the spring, and thenthe spring c' is tightened upon the shade byturning the thumb-screw d in 4the proper direction and bringing the endsof spring c toward each other. AWheni-tis desired to loosen the shade,the thumb-screw is turned in the opposite direction.

It will be observed that the' screws c /l lll C alle screw-threaded onlyin the spring c', passing loosely through the ring c, This is to allowthe necessary slide forward and back of the ring c, incident to itsadjustment 'by the bolt d.

h is the chimneysupporting ring, to which or with which the springs Itlc k are connected.

m indicates a coiled spring surrounding a bolt, the same being placedwithin the casing o, and together constituting the means for holding thechimneysupporting ring h in po- .siticn when hinged at one side, asshown in Fig. 2. The bolt referred to is indicated by x. When this ringis in -its normal position, .the bolt shown passes within a socket, fromwhich it is readily withdrawn by releasing the same from the pressure ofthe spring when .it is desired to raise or remove said chimneysupportingring.

The special advantages of the construction constitutingmyinventionconsist in the readiness withy which I'arn enabled to remove and replacethe shade ofthe lamp, as well as the degree of security which isattained by holding such shade in the manner shown.

It not infrequently happens that lampshades are so loosely held inposition that the motion of the car or steamboat tends to break thesame, as well as to create a disagreeable rattling. MynewVconstructionboth prevents rattling and guards against any liability ofthe breaking of the lamp-shade. The further ad-V vantages are to befound in the means shown for permitting the raising of the chimney ofIOO the lamp high enough to clear the burner, so that the chimney can beremoved or replaced in thelamp without removing or dis turbing eitherthe lamp or the shade, and, still further,in the use of thehinged capdescribed, having in connection therewith the springs shown, whichsprings act to steadily support the chimney when the cap is in positionand prevent any motion or rattling.

rIhe shade-holder is preferably attached by braces to the lamp-frame;but it may be entirely separated from the lamp and secured to theceiling of the car, or otherwise sup-v ported.

The chimney-supporting ring, while preferably provided with springs le klc, such as shown in Fig. 2, may have other suitable appliancesconnected therewith, which will operate within said ring for securingand steadying the upper portion of the lamp-chimney when in place. rlhischimney-supporting ring or cap I prefer to hinge to the shadeholder, asshown in Fig. 2; but it may be fitted separately and held in place byany suitable means so as to be capable of being detached. Vhen it isdesired to release the chimney from the retaining action of the springs,it is only necessary to turn back' or remove said ring in the mannerindicated in Fig. 2.

The operationof the construction which I have invented is as follows:When it is desired to either place in position or remove the lamp-shade,it is only necessary to open or close the shade-supporting spring bymeans of the screw cl.

I am aware that it has heretofore been proposed to mount that part 0fthe lamp-frame carrying the shade and furnishing a support for thechimney upon hinges, so that all that part ofthe lamp may be raised, ifdesired. This is a clumsy construction, since it is inconvenient to becompelled to raise the shade whenever it is desired merely to remove thechimney, and Ido not claim it. I, on the contrai-y, propose to hinge thechimney-supporting part of the frame immediately to that part whichsupports the shade, so that this alone need be moved when it is desiredto lift the o chimney.

\Vhen it is desired to elevate the lampchimney so as to raise the samefar enough to clear the burner, it is only necessary to either llift orremove the chimney-supporting ring or cap so as to release the chimneyfrom the retaining force of the springs. rIhe number of springs requiredfor the office indicated is preferably three; but the number may bevaried. The chimney-supporting ring or cap may be turned down whenhinged or placed in position when separately attached before the chimneyis returned, or said chimney may be first placed in position and thesupporting ring or cap either turned down or placed over the same.

Any person familiar with thc construction of lamps will readilyunderstand the material which will be best adapted for the parts which Ihave described and shown.

My improved construction has the merit ofcheapness,simplicity,anddurability,and,while adding materially to thequalities required in a convenient and serviceable lamp, in no waydetracts from the appearance of the same, but, to the contrary, is anaddition thereto in the respect last indicated.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, 1s-

l. The combination, with the support of a car-lamp, of the ring c,attached thereto, the chimney-supporting cap h, hinged to the said ring,the springs 7c k k, bolt and spring m, mounted on the cap h,substantially as described and shown.

2. The combination, with a car-lamp support, of a shade-holder attachedthereto, and a chimney-supporting cap hinged to the shadeholder andprovided with chimney-holding springs, substantially as described andshown.

3. The combination, in a shade-holder, of a circular spring forembracing the shade, the ends of said spring being provided withreversely screw-threaded holes,with a bolt provided at its two ends,respectively,with screwthreads of opposite inclination and adapted toengage with the threads of the holes in the spring, substantially asdescribed and shown.
